The story about the 6-3, 300 lb. sheriff's wife made me look. Check out this list of tall women. I wouldn't have thought the 6-5 would be tall enough to get you on this list, but then again when I think about it I don't think I've ever seen a 6-5 woman.

Here's an interesting photo of WNBA player Margo Dydek, too. She's on the left.
